The problem is not that it's a semi-synthetic. The problem is that it's a 20W-50 oil. Your engine will live a long and happy life on 5W-30 dino oil.

And if you're driving a Porsche or VW, that's fine. Also, keep in mind that companies often pay manufacturers so they can be the "Official Oil" for the brand.
